Description: The entrance to Oven Rock Cave is situated in a hillside on Great Guana Cay. From the 15 m wide, 2.5 m high entrance, a 40 m long dry chamber descends over breakdown to a tidal anchialine lake. The 1.5 m deep lake extends around the sides and rear of this chamber. An underwater room trending off from the lake is well decorated with large stalagmites at depths to 9 m.
